' Hartford, in the county of Hartford and State of Connecticut, haveinvented certain newand useful Improvements in Typo-- graphic Machines,of which the following 1s a specification.

' This invention relates to typpgraphic machines of that class in whicht e impression devices are assembled in one or more sets, the

several setsv being selectively shiftable and this shifting of theentire assemblage of impression devices in which the ski a serving tobrin the selected device to the wcrkin point 0 the machine; a

An 0 Ject of the present invention is to furnish a machine of this classwhich may be provided with a large number of types or dies, and isadapted or making a large number of im ressions, while keeping the sizeand mass oft e impression mechanism relativel small and capable ofoperation at a big velocity.

In carrying out my invention a plurality of impression devices orrolling impressors disposed in one or more sets are employed capableoil-axial or sidewise movement toward and away from a fixed plane; Topermit of this movement and other motions of which they are be. able,the impressors are mounted as a who e upon one or more seetionalcarriers each comprising a number of separate and independently movablesections, one for each of the aforesaid sets of impression devices; Inthe particular embodiment set forth in the drawings hereto attached,the-several sections of a sectional are carrier are afiixed torespective shafts which are concentrically dis osed with respect to eachother. When t e im ression device carried u on anyparticular s aft'is to-be operated, t shaft when it is started rotating (or at some other timebefore an impression is. made) is shifted with other shafts in that setlengthwise-or axially to its roper operative axial position, and after te impression has been made the shafts are' returned to theiroriginalaxis-l SA. similar oration takes place when another of pr carried by ashaftin that set is to be Specification of Letters Patent.

The invention embodies, also, in combination, with the foregoing, aselective mechanism, whereby a particular type or die upon all-others,the operation of any type or die being therefore under control.

Fig.18 is a similar view of the immachine, but the invention is not limited,it will be understood, to such particular embodiment, it beingapplicable in. whole or in part as respects its various features totypographic-machines in general or machines in which an impressiondevice is designed to operate upon or affect a certain surface.

The impression devices of this machine are rotary or rollinginlpl'cssors, consisting of one or more main parts or carriers eachcomprising a plurality of sections upon which are mounted one or moreimpression types or dies. These parts are disposed, according to thepresent invention, when in their normal.

or inoperative positions, in such relation to a fixed plane (hereinafterreferred to as the o erative plane) as to be shiftable axially tereinto, and if a main carrier embodying a set comprising three carriersections is employed, as shown in the drawings attached to thisspecification, a carrier-section may be located on each side of saidplane while a third is normally in that plane. While threecarrier-sections are shown as forming a set, it is evident that thisnumber may be increased or diminished ,without departing from the spiritof the invention. All the carrier-sections in a set are shifted axiallyto bring any particular one of such sections normally at theside intothe fixed or operative plane, (see lines PP, in Figs; 6, 7, 8, and 9).For this pur ose they may be conveniently affixed to s afts which extendon one side of the operative plane and are fitted the one shaft torotate within the other;

I Each main carrier is adapted to have both a movement in a closedcircuit ororbital path, and, at times, a rotary motion about its ownaxis. In the particular instance illustrated, this closed circuit ororbital motion is that of revolution about an axis exterior tothecarrier, and for the purpose of conveniently enabling this double motionto be attained the shafts 4, 5, and 6 carrying the sections 1, 2, and 3,respectively, of a set are shown mounted in a turret or rotary carrier 6whichmaybe rotated by the shaft 7 through the medium of a pulley orbandwheel 8"from a'convenient source of power. The bearings of thisshaft 7 are supported by a suitable fixture or fixtures which, in thepresent instance, are constituted by the protecting casing 9 inclosingthe mechanism.

Such a number of sets of carrier-seciions as are desired, within thecapacity of the turret, are disposed thereon, being allixed to suitablesets of shafts. each set may be journaled in an arm 17 extend ing fromand secured to the shaft 7, and the inmost shaft 5 at one end in an arm17".also extending from and secured to the shaft 7. If, now, theintermediate shaft 4 of the set is journaled on the inmost shaft 5 andextended toward the operative planein the space between the outer andinmost shafts, the

The exterior shaft 6 in shafts afford mutual support for each other.Theseveral arms 17 and 17 extending from and secured to the shaft 7 inconjunction with the latter may be regardedas forming the turret 6 7Each set of associated shafts 4, 5, and 6 is adapted to have anindependent rotary motion imparted to each of its component shafts inaddition to the orbital motion which the set may have by virtue of therotation of the turret 6 and for this purpose to each shaft there may besecured a gear or toothed wheel 18 engaging at times with a driver, inthis case an internal gear-wheel 19. There is a gear-wheel .19 for theseries of inmost shafts 5, another for the series of intermediate shafts4, and another for the series of outer or exterior shafts 6. Eachinternal gear 19 is shown as being secured to the casing 9, and itaffords a positive means when a gear-wheel 18 is engaged with it foreffecting a rotation of the gear-wheel.

The endwise or axial movement of each shaft 4 and 6 in each set forbringing the corv responding carrier-se -lions into and withdrawing itfrom the operative plane is utilized for engaging the gear-wheel 18 onthe shaft with and disengaging it from the corresponding driver 19. Toeffect this endwise mo vement in one dirccti on there may be combined,as shown in the present instance, with each series of exterior shafts 6and each se ries of'inmost shafts 5 an actuating member or cam 20, withwhich there is adapted to cooperate a coacting member or cam-arm 21 oneach shaft in the corresponding series for shifting the shaft toward andbringing the-corresponding carrier-section into the operative plane. itwill .be manifest that since the rarrier-sectirms supported by oneof thementioued series of these shafts, in the illustrated and describedorganization, lie when in their normal positions upon one side of theoperative plane and the carrier-sections sumiortcd by the other seriesof shafts lie upon the other side of the operative plane, that thetwo'series of shafts move in opposite directions in approaching theoperative plane. Hence the cams 20 for the two series will face inopposite directions. For returning the shafts in the two series theremay be an actuating member or cam 22, one for each'series.

with which is adapted to co-operate a com-iing member or cam-arm 23,projecting from each shaft which accomplishes the shifting of a shaftbiwlnvard and the withdrawal of the corresponding carriensectionfromsaid plane. These cams?! for the two series of shafts also, it will beunderstood, are oppositely facing. Each arm in one of these two seriesof cam-anus 21 and 23 here shown to be 438111- arms 21, may have itsoperative surface arranged at the end of a flexible or spring-likestrip, which method of supporting the operative portion will tend tosuppress theviolence of the shock when the contact.

When the carrier-sections 'on any set of parts come in associated shaftsare in their normal or'inoperative positions the intermediatecarriersection attached to the intermediate shaft 4 lies in theoperative plane, as here organized and asshown in. Figs. 3 and 6. Henceit is i not necessary to shift the intermediate car-' lengthwise-"rier-section of a set axially when it is desired to set it in rotation,and in fact such a shifting, it is evident, would prevent its operationat the designed point in the operative plane. To effect the rotation ofany intermediate shaft 4 andthereby its attached section 2, thegear-wheel 18, for this purpose, is shown mounted upon a. sleeve movablealong the. intermediate shaft but fixed thereto so .easethere may becombined with,the. series of sleeves "an actuating member or 'cam 20,

withwhich is adapted to coeoperate' a coacting memberor cam-arm 21extending "from each sleeve and similar to the cam and camarms 20 and 21already described, although Tss- -.are',notherein shown asbeingsupported theioperative portions .of the cam-arms 21 upon, flexibleor' spring-like strips. For the several sleeves-iirthe'oppositedirection there may be an factuat'. memberor cam 22 with which isadapt'eto cooperate a coacting member or cam-arm 23 oneacli sleeve similar tothe cam and cam- 15131 22 and 23 already described.

For holding-each sleeve 25 in a position to which it may be adjustedaxially, and to prevent its axial movement when either the exteriorshaft 6 orlthe inmost shaft 5 of the corresponding set is shiftedtobring its attachedcarrier-section into the operative plane,'there isshown a lever 31 pivoted at 32 to a 'boss 33upon the shaft 7 and pressed2 downward by a spring 33 against a raised yer from the side to the top.vice versa, but not preventing it when su-fiiportion or rib 34 on thesleeve. This lever 31 and rib 34 are preferably formed to engagewitheach other that their coaction will be such as to resist thedisplacement of the leof the rib, and,

cient forceis exerted through the operation of the. shifting cams 20 and22 to e act the transfer.

4 The-cams 2O and-22 for each series of exterior inmost shafts andtheicams 20 and 22 for the series of sleeves 25 may be attached to thecasing 9, and are located in the-proper positions to co-ope'ratewiththeir respective arms, While the distance each causes a shaft or sleeveto move axially is not sufficient to carry the other arm of that shaftor sleeve which coacts with the other cam be ond the point where contactof this "arm wil take place with its cam when the shaft or sleeve hasbeen swung around to render the arm operative.

- The two cams 20 and 22 for each series of shafts and the cams 2'0'iand22 for the series diametrically, opposite sides .of'the circle in whichthe operative ends of their cam-arms move, while each cam is of. alength suflicient to insure; the contact of the coacting arm with it asa shaft or sleeve rotates about .its

own axis and revolves about the axis of the of sleeves 25 are arrangedsubstantially on turret. As a result a movement of the shaft or sleeveto jand fro for each rotation of the turret 6 is produced.

' For each series of shafts 4, 5, and 6 there will'be provided some formof device for resisting, to a considerable degree, anv axial movement ofthe set for the pur ose of holdthe set of shafts in an axia .position to1n 'wldich they may be shifted. For instance, a

spring-pressed detent 101 may be urged into either one of three grooves102, 103, 104, corre 'sponding to the axialpositions of the shafts andformed in a disk 105 attached to one of the shafts of a-set. If thesides of these grooves are made slanting and the detent corresponds inform the pressure inward of thedetent will cause a degree of end thrustin the shaft tending. to complete .the operation of the shifting cams.20 and 22. A' collar afilxed to each inte'rmediateshaft 4 is shown forpreventing the axial movement of the exterior shaftfialong theintermediate shaft While the corresponding movement of the latter shaftwith respect to its inmost shaft 5 may be prevented by similar means.

, "Some "form,;of' a ping the rotation o a shaft in a determinateangular position when itsgear-wheel 18 has been thrown out of en agementwith its driving-gear 1 9 I will also fprecision -brake for stopeprovided. The 1 'device shown in the present instance comprises for eachintermediate shaft an elastic finger 27 secured to the boss 33 andextending across the path and tending to'retard the, revolution of the.pins'26 before'mentioned. A similar device-1s employedv for the othershafts, and consists of asimilar elastic finger 27 for each exteriorshaft-Gprojecting from the shaft 7 and extending into and tending toretard the revolution of pins 26' extending from a flange 26 projectingradially from shaft 7 and a. similar elastic finger 27 similarly relatedto pins 26 projecting radially from a flange 26 upon eac inmost shaft 5.

For initiating the rotary movement of the individual shafts 4, 5, and 6and sleeve 25 for the purpose of turning the arm 21m 21 into a positionin which it may coact with its proper cam each shaft is provided with astartingarm 28 operating substantially in the manner set forth inPatents Nos. 431,371 and 57 3,620 granted to me on April 16, 1889, andDecember 22, 1896, respectively, which maybe consulted for a detaileddescription of its con struction and mode of operation A starting-arm 28on each shaft or sleeve maybe arranged in a different transverse planeto that of the starting-arm on any other for a purpose that will beexplained later.

Referring now to certain selective devices whereby a particular sl'iaftmay be set in retation and the amount of such rotation that shall occurup to a fixed point where an impression device is to operate be undercon'-' trol, these results may be attained by the employment ofa seriesof latch mechanisms, the tripping of anyone of which will cause areciprocating latch or bolt to protrude into the path of a revolvingstarting-arm which engages therewith and turns the shaft in its Ybearing, itself resetting the latch. in the manher set fort'h in theaforesaid patents.

An suitable mechanism of this character may bh employed or thatparticular organization thereof to be described.

. Each latcl. mechanism as herein shown is operated by means ofaspring-returned rocklever 29,. actuated by pressure upon a key 29* atits outer end. A number of these rock-levers 29 is shown correspondingin number to the types or dies uponthe im pressors. They may all befulcrumed at the rear of the casing 9, for instance, by a rod 150, andmay each have a push-rod. 30 extending upward through an opening at thefront of the casing and provided at its'top with a finger-piece or key29.

There will be as many latches or bolts in the latch mechanisms designedto actuate any single shaft supported on the turret 6" as there aretypes or dies upon the impressor affixed to that particular shaft.Furthermore these latches are arranged at ,different distances from thepoint at which the types or dies operate or impression is made for thepurposeof initiating the rotary movement of the shaft at differentdistances from said fixed point.

The latch mechanisms for initiating the rotary movements of any singleshaft will all be located in the same plane in which the starting-arm 28thereon swings, while this latter is made of a width sufhcient topreelude its passing to one side free of the latch mechanism despitetheaxial shifting of the shaft to which the arm is attached by the action'o'f the cam 20, or 20.

i I In Fig. 3 there are shown twelve separate latches substantially inthe same plane, but

i of course this number may-be increased or diminished according to thenumberof types have. Each series of latches'for operating any one shaftis conveniently located in a latch frame 32 so formed and located as totherein to be arranged circularly or concentrically with reference tothe axis of the turret 6 Each latch mechanism comprises a bolt or latch33fitted to slide through suitable openings in the latch frame towardand away from the turret axis. Each latch, in the present instance, isheld in its inoperative or retracted position by anotch 34 there onwhich fits overthe edge of an opening in the latch frame and preventsthe latch from being thrown inward under the tension of a spring 35, byreason of the contact of the side of this notch with the shoulder 35 inthe latch-frame opening. A spring 36 normally holds this notch 34pressed against the shoulder 35" of the opening in the frame, but theopening is wide enough to permit a sufficient lateral movement of alatch when the notch is pressed away from the shoulder for a latch toclear the latter. Suitable intermediate devices are inserted betweeneach rock-lever 29 and its corresponding latch or bolt As shown in Fig.4, some of these intermediate devices comprise each an angle-lever 37pivoted to a stud 37*, extending from a llangeSS of the latch frame 32,one of the arms of the angle-lever being connected with itscorresponding rock-lever 29 by a link 38, while the other arm of saidangle-lever made in the form of a finger 39 which passes over aprojecting toe 39 on the latch. A downwardqnovement of afinger pressesthe notch 34 away from the shoulder 35" and permits the correspondinglatch to be thrown inward. Others of the latch mechanisms are shown asconstructed to be each tripped by means of a finger 40, pivoted orotherwise connected to a rock-lever 29, while it is properly guided bymeans of pins l()l0 on opposite sides thereof, and has itsangularlyextending upper end 40" lying above the extremity of the latch.

The various rock-levers 29, angle-levers 37, links 38", and fingers 40,concernedin the actuation of any one starting-arm are made of such formsand dimensions aswill permit the motions of the. several rock-leverswhenlying side by side as shown. to be transmitted and serve tooperatethelatches or bolts ar ranged in the plane of thatstarting-arm.

The several latch fra1nes'32 for supporting the several sets of latchmechanisms may be conveniently held in placelupon a rod 42, extendinglengthwise of the machine.

A step-by-step motion or a motion of any other character to properlyfeed the material whose surface is to be impressed or acted upon may. beimparted to such material by any suitable means or ,that herein shown,which is designed to accomplish a stcpdrvor dies it is desired that eachimpressor shall 1 step or intermittent movement. Supported permit theinner ends of the latches or bolts arm 46 may desired, as shown in tothis particular position. while the rock-shaft 48 is in t mined positionand is not being -tact with and be moved by a shoulder upon a feed wheelor disk for the purpose of accompl shing this feed movement. Normally,(assuming that the turret 6 is 'rotatin the operative plane to eiiect anImpression, andt at thegear-wheel 18 on each sleeve 25 is out of itsengaging position as shown in Fig. 3) there is no contact of this pin 47with a shoulder upon afeed wheel or disk, but when-a carrier-sectionhas'been shifted into the operative plane or the gear-wheel on a sleeveinto engagement contact willbe made sometime during the orbital androtary movement of the carrier-section between a shoulder upon acorrespondingfeedwheel or disk and a pin or projection-47.

There is a swin lever and a floatingarm 46 supplied wit for each of theseries of carrier-sections, or, in other words, each series of-inmost,intermediate and exterior shafts. These swinging levers 45 are afiixedto-a rock-shaft 48 mounted in suitable bearings, which may be supportedby the casing 9.- The rotation of the rock-shaft 48 in. one directionpast a predetermined point is prevented by a stop, 13, while a spring 51constantly ur es the shaft ormalll or pre eterturned in its y afloatingbearing, the direction-taken- Fig. 4, where it is seen po ntingon that side of the turret axis which 1 1s moving toward itwhen theturret is rotat- The floating-arm 46, however, may not in 05y be movedforward in the manner pomted out below to turn the rock-shaft 48, but

tion relative to 4s may also be deflected from its normal posithe lever45, being designed to return to such normal position when free to do so.To bring about this return it may be provided withan elastic finger 52confined between stops 52 52".' I a The feed disks or wheels mentionedas oooperating with the pins 47 may each consist of a separate andindependent disk attached to each shaft in the series of exterior andinmost shafts and the sleeves 25on, the intermediate shafts 4, or thegear-wheel 18 upon each shaft and sleeve may perform the function ofsuch feed-disk as herein illustrated. The shoulder stated as coactingwith a pin 47 maybe formed as shown by notching the radial face of eachgear-Wheel 1ndicated generally by 53, or such shoulder may be formed bythe bottom of the gear-wheel tooth which for this pu pose may beregarded as forming a notch.

bach floating-M11146 is to that set of feed-Wheels, or, as herein s own,gear-wheels 18, with which it is designed to but i that nocarrier-section has been shifte into a pin or projection 47 be, if afeed before impression 1s,

arranged ad'aoent co-opeiate, and upon that side of the gear 4 tact ofthe pin 47 takes place with a shoulder on the feed or ear wheel;

The lateral reedom of movement of each pm 47 permits it to readily seatitself in the ottoin of a notch 53, whereupon further orbital and rotarymovement of the earwheel 18 causes the elevation of the oating-arm 46from which the pin 47 extends, and the consequent artialrotation of therockshaft 48 with w 'ch it communicates. Finally, as the wheel;continues its double circular movement, the pin 47 is rolled. out ofits. notch, the floating-arm 46 simultaneously deflecting with referenceto the swinging lever 45, and the sp 52 return the. parts" to t eiroriginal positions.

place if so desired each time the engagement of a gear-wheel 18 with itsdriver 19 occurs, and hence a feeding movement result for 51 and thefinger.

A movement of a floating-arm 46 may'take each movementofac-an'ier-section into the operative plane. A. variationin the amountor degree of this feeding movement may be desired, for instance, where anumber of tlypes or dies of varying width are used.

his may be secured by altering the radial depth of the notches upon thefeed-Wheel or gear-wheel 18, resulting therefore in the turning of therock-shaft 48 through different arcs. It will be understood, therefore,from the foregoing that the entrance of a pin 47 into a particular notch53 corresponds to the ed or impression point. ntermittent rotary motionmay be imparted to a feed-shaft 54, here shown as being arranged at thetop of the casing 9, from the rock-shaft .48, by means of a system ofgears 56 at the side of the casing, which may include a pawl-andratchetmechanism 57. V

The resent embodiment of the invention beings own as'a tewriting-machine, the printing platen may 6 in the form'of a rotarycylinder 60, guided to move with its companion pressure-rolls 61, 61, oranyother desired number, endwise. along the guidebars 62 and 63 entering64 and 65 extending from the casing.

For the purpose of permitting an endwise movement of the rotary platen60 and the pressure-rolls 61, 61, they may lie between side frames 66and 67, secured together by a stretcher-rod 68. The feed-shaft54 may beof any preferred construction to effect the endwise intermittent feedingmovementof the rotary laten 60. As shown, it is formed with a ratchetthread 69, with which engages an arm 70 extending from the frame :67;This arm 70 will preferably bep voted to-tlia frame and pressedcipwnward mto'engagee appearance of a particular type or die at thestationary brackets ment with the ratchet thread 69 by a spring 71, forinstance, which will permit a disengagement from the thread by theexertion of a pressure upon the outer end of the arm. The platen ,60 mayhave the usual return spring (not shown) while the inclined surface ofthe ratchet thread 69 allows the arm 70 to slide endwise on thefeed-shaft when the platen is pushed backward along its guides. Aratchet mechanism may be provided for imparting a step-by-step rotationto the platen 60, and itmay comprise a pawl-open atin handle 7 2carrying a spring-pressed paw 73 engaging with a ratchet-wheel 74affixed to'the platen or an extension thereof,

While a more or less continuous rotary movementmay be given to theplaten'manually by means of a thumb-wheel75, secured to the guide-bar62, which for the purpose is mounted to turn in the end brackets 64 and65, and is provided with a longitudinal groove -76 into WihlCll extendsa pin (not shown) projecting from the platen 60'. A retaining devicedesignated by 7,8 is shown for holding the/platen 60 in a desired rotary'posltlon. Agpaper guide, designated by 79,

may also be used for retaining the paper in the proper position on theplaten.

' ing thus very nearlyfa complete revolution The usual ink ribbon,designated by 80, may have the take-up roller 81 of the mechanism drivenin any suit able manner-for instance, as herein shown, through a system.of gears 82 from the feed-shaft 54. Prefer- .ably, the take-up roller81. has a frictional connection with its driving-shaft 83 to permit of areverse movement of the roller around its moving driving-shaft when theribbon 8,0 is wound back upon its supply roller by means of a crank 85.The supply roller 84- is prevented by suitable means (not shonn) fromoperating too freely. These requirements are usually fulfilled by theordinary inking ribbon-device and the mechanism need not therefore behere more fully described.

It has been stated thatthe type or'dies upon each carrier-section isdifferent from the types or dies upon any other. If this is the case itmay happen upon'the trippingof a latch mechanism to permit its latch toprotrude into the path of the corresponding starting-arm 28, thatthis-particular arm has just passed the point at which it would beactuated. and. set; -motion. therefore, ente'nuponits rotary motionuntil it has again reached the projected latch, makabout-the axisrofthe. turret 6?, It may, howeverfbeadvisable to reduce this possiblemaximum periodelapsing :fromthe time of the manipulation of alatchmechanism until impression shall be made, and for this purpose anyimpressor mounted upon the series of carrier-sections formed by thesections attached to one or morecf the'series of shafts may have oneormore duplicates inthat It will not,

series. In the present instance the carrier sections upon theintermediate shafts 4 are provided with impressors which are allduplicates of each other, while the impressors upon thecarrier-secctions of the exterior shafts 6 are arranged in pairs, thoseon the diametrically-opposite shafts being duplicates. All theimpressors on the c'a'rriensections to the inmost shafts5 are,however,disward after a st arting-arm 28 has passed, then the arm of the sh aftwhose section is provided with-the duplicate impressor will be actuatedand thus the necessity is avoided for the starting arm which has justleft the actuated latch mechanism to make a complete revolution beforethe desired impression can be made. i

The customary space-key is shown at which operates through anintervening rocklever 29, latch mechanism, and starting arm 28 similarto those that have been described to initiate the rotation of a shaftfor the purposeof shifting the same toward the operative plane.

Although a feeding movement will therebv take place in the manneralready described, the relation between thetypes or dies and the blankspaces on the particular carriersection actuated, and the amount thatsuch carrier-section is caused to rotate by the Knit- IIO 2, and 3 totheir respective shafts, whereby the ready detachment of section fromits shaft is permitted for the purpose, for instance, of attachinganother in its place and without the necessity of changing the relasembling them. Each such section is-secured to its shaft by attachingthe same to a radial .120 .tion of the shafts and subsequentlyreasflange upon the shaft, and these flanges are of such relativediameters'as net to interfere w th the removal of any section when theouter ones have been: takenoff. The flange 6 oft'he shaft 6 ispreferablyprovided. with Y an-annular groove or channelfi forming a Yshoulder. overwhich the sect-ion 3 fits and against which it is forcedarid held in place by the fastening screws 6', c entering threadedenings in the flange 6 and having their leads overlapping the section.Similarly the intermediate shaft 4 is provided with a radial flange 4whose outside diameter is not greater than the diameter of the bore ofthe section 3. This flange 4 like wise has an annular groove 4 forming ashoulder against which the section 2 is clamped by fastening screws 4 4entering threaded openings in the flange and overlapping the section. Itwill be noticed that the unbroken flange 4 is of such diameter as tocause it to extend over the fastening screws 6 ,6 and hence it may berecessed as shown at 4 4 to expose these screws. Similarly the inmostshaft 5 is provided with a radial flange 5 whose outside diameter is notgreater than the diameter of the bore of the section 2. This flange 5likewise has an annular groove 5 forming a shoulder against which thesection 1 is clamped by fastening screws 5, 5 enterin threaded openingsin the flange and oveflapping the impressor. Portions of this flange 5may be also removed, as shown at 5", 5 to expose the fastening screws 44 Preferably the various fastening screws will be let into countersunkrecesses to enable the sections of a set to be closely assembled. It isevident that the flanges of the different shafts perform a furtherfunction than constituting means for the attachment of the sections, asthey,act as stops to limit the relative lengthwise movement of theshafts.

i mg'oft'he starting The operation of a machine constructed asillustrated may be described as followsAssuming that a key has beendepressed, thereby actuating the rock-lever 29 to which it is 1attached, the corresponding latch 33 is permitted to be thrown inward bythe attached 5 ring 35, and the first starting-arm 28 in the I p ane ofthat latch to reach itwill engage with its end.- The continued'rotationof the turret 6 causes the engaged starting-arm to swing around, as alsoits shaft, (assuming that either the series of inmost or the series ofexterior shafts is actuated,) untilby the contact of the cam-arm 21 withthe inclined surface of cam 20 the gear-wheel 18, its shaft,

while the gear-wheel 18 simultaneousliv -meslies with the driver 19. Thecorrespon ing detent'lfll has in the meantime sprung intothe groove 102,maintaining the parts in this axial'positiqn; Rotation of the said shaftnow takesplace, the continuous swingthe meanat type or die $11118 resetthe law-i133,

the pin 47 is free from the particular notch into Whichit enters toeffect the feed the shaft 48, etc., are returned. to their normalpositions by the spring 51 and elastic finger 52. Soon after this,byreason of the-continuedrotation and revolution, thecam-arm 23 contactswith the cam 22, and the shaft being free to move endwise is shiftedback to its original position, the retaining detent 101 wheel 18 iswithdrawn from the driver 19 si multaneo'usly with this return movementand the shaft brought to rest inits normal angular position by theelastic finger 27 assisted to some degree b the action of the detent101, as aforesai Coincidently with the disengagement of the gear-wheel18 the carrier-section has been shifted from-the 0perative plane leavingthe intermediate carrier-section therein. If, however, a carriersectionon an intermedlate shaft 4 1s the one that will respond to thedepression of the key this shaft is not shifted axially, since thecarrier-section attached thereto lies normally in the operative plane.The only-result of the engagement of the cams 20 and cam-arm 21 duetothe swinging of the starting arm 28 of the sleeve will be to shift thelatter axially along the intermediate shaft and carry the gear-wheel 18attached to the sleeve into engagement with the driver 19. A rotation isthen imparted from this gear-wheel 18 to the shaft b means of'the pins26, and an impres sion followed by a return movement ensues in themanner already described.
